Did you try 1.0.5? I'm not sure of the problem, but if it was with the archive and the files included, then that could work.
Next step if that doesn't work: On your server, in the /suriname/zen directory, rename `"functions.php"` to `"functions.txt"` -- this will make Zenphoto stop working, but it will allow me to see the contents of the functions.php file you have and try to find the problem.
Thanks!
